HORATIO V. PHILPOTT, OF BUFFALO, TEXAS.

GATE.

'SPECIFICATION forming part of Letters Patent No. 571,237', dated November 10, 1896. Application led May 16, 1896. Serial No. 591,835. (No model.)

To all whom it may concern.-

Be it known that I, HoRArro V. PHILPOTT, #a citizen of the United States, residing at Buffalo, in the county of Leon and State of Texas, have invented new and-useful Improvements in Gates, of which the following isa specification.

My invention relates to a gate of the general character described inLetters Patent Nd 363,964, granted to me May 31, 1887, in which j by the operation of suitable lever mechanism the gate will be raised on or along a central pivot and then gravitate and 'swing to an open or closed position automatically on release of the lifting devices.

It is among the objects of my present invention to improve, simplify, and cheapen the lever mechanism through which the gate is` to be lifted and the devices for swinging the gate upon its support by the action of gravity. A gate of this kind is especially adapted for farm use and in situations where it is usually necessary for arider or driver to dismount in order to unfasten and swing the heavy gate open or shut; but the invention is also applicable to gates in other places and whether the road is intended for foot-passengers or vehicles.

The invention consists in the features of construction and novel combination of parts in an automatic gate, as hereinafter more particularly described and claimed.

In the annexed drawings, illustrating the invention, Figure l is an elevation of the gate with its operating mechanism. Fig. 2 is a plan of the segmentally-slotted and toothed cap or disk on the top of the central gate-post. Figs. 3,4, and 5 are elevations of the upper part of the central gate-post with toothed cap or disk attached, showing the top beam of the gate in cross-section and in progressively different positions of operation. Fig. 6 is a plan of the gate. Fig. 7 is a view of a latch and stop for the gate. Fig. S is aview showing how the lever mechanism of the gate may be operated from a distance.

Referring to the drawings, the numeral 1 designates the gate, and 2 is a post on which `the lower gate-beam 3 is centrally pivoted.

The top gate-beam f1 pivots on a rod or standard 5, that rises centrally from the post 2 and is extended to any required height.

On the top of the post 2 and surrounding the standard 5 is mounted a shiftable disk or cap 6, in which several segmental slots 7 are formed. is passed into the top of the post 2 a screw or stud 8 to hold down the cap 6 and allowit to have a slight oscillation limited by the length of the slots, each screw or stud being provided with a head of sufficient size to overlap the edges of the slot through which the stud projects.

At the peripheral edge of the disk or cap 6 is a series of curved teeth or projections 9, having each an inclined upper surface 10 and a pocket 11 at the foot of said incline and cut under the adjacent tooth. The periphery of the disk or cap 6 is provided at suitable intervals with laterally-projecting pins 12, that take the pressure of springs 13, the lower ends of which are attached to the post 2 by bearings 14- or otherwise. By the tension of these springs the cap or disk 6 will be returned to its normal position when moved therefrom in the operation of the gate.

There is secured centrally to the under side of the top gate-beam 4 a plate 15, provided with depending forked arms or bearings 16, in which are journaled rolls 17, arranged to engage and operate upon the curved or inclined teeth 9 of the post cap or disk 6 in swinging the gate.

For the purpose of lifting the gate along' the post 2 and rod or standard 5 there is fastened to the top gate-beam f1 a yoke 18, having in its top a central perforation for passage of a swivel-bolt 19, the lower end of which is headed to loosely connect it with the yoke. The upper end of this swivel-bolt 19 has an eye 20, to which is fastened the central portion of a rope or chain 21, the ends of which are fastened to disks 22, mounted on pivots 23 between two parallel and horizontally-arranged beams 24, supported on posts 25, that may be arranged either in line with the fencing or at right angles thereto, .as preferred. Each pivotallysupported disk 22 is provided with an upright arm 26, to the upper end of which is secured a rope, chain, or wire 27, extended to a convenient position from which to operate the vertically-movable and horizontally-Swingin g gate.

It will be seen that by drawing on either IOO arm 26, through its cord, chain, or wire 27, the attached disk 22 will be turned in such direction as to cause the rope or chain 21, swivelbolt 19, and yoke 18 to lift the gate 1 along the central post 2 and standard 5, and as the gate rises the rolls 17 impinge against and travel beneath the overhang-ing points of the teeth 9, thereby causing the post cap or disk 6 to turn a short distance against the tension of its springs. As the rolls 17 pass the points of the inclined teeth 9 the springs 13 throw the cap or disk G to its former position, bringing the inclined upper surfaces 10 beneath the rolls. lf now the arm 2G or attached chain or wire 27 is released, the gate will descend by gravity, and the rolls 17, traveling down the inclines 10,will cause the gate to swing through one-fourth. of a complete revolution to either an open or closed position, as the case may be, the rolls 17 coming to restin the undercut portions or pockets'11 of the cap-teeth.

It will be observed that either arm 2G will operate the gate either to open or close it. Either arm may be operated to open the gate, say, from one side of a fence, and then after passing through the gateway a repetition of the operation with the other arm will close the gate.

.The posts 25 may be erected either at the sides of a road or gateway in line with the fencing, or they may be placed at right angles with the fence. There are also preferably provided other posts 28, erected at right angles to the posts 25 and in line with the central post 2, on which the gate moves. If desired, these posts 28 may form part of the fencing, in which event the posts 25 will-be placed in the road, or the relative positions of the posts 25 and 28 in ay be reversed according to circumstances and the particular situation in which the gate is to be operated.

Each end of the vertically-movable and horizontally-swinging gate 1 is provided with a `rigidly-attached pin 29,projecting inline with the gate and adapted to form part of a fastening for the gate when swung through onequarter ofv a lrevolution to either an open or closed position. To act with these pins, there is provided on the inner side of one post 25 and one post 28 a gravity-latch 30 and a stop 3l, between which either pin 29 is adapted to engage.

lV hen thek gate has swung a quarter of a revolution,one of the pins 29 will come in contact with the lower portion of one of the gravity-latches, and will swing it aside and pass beneath it to the space between the latch and the stop, thus arresting the movement of the gate in its open or closed position and holding it fast until the gate is again lifted. The stop 31 may have an angular form with its hori- `zontal portion arranged beneath the lower swinging end of the gravity-latch 30 and so close thereto as to cause the lower wedgeshaped end of the latch to bind in one direction and thus lconiine the pin 29 after it has passed inward beneath the latch. On lifting the gate the pin 29 will pass upward from between the latch 30 andstop 8l, and thus permit the gate to swing with the traveling of the rolls 17 on the inclines 10, as before described.

Obviously, the operating chains or wires 27 may be extended in proper directions to connect with spring-boards (not shown) that may be so arranged as to be depressed by the wheels of a vehicle and thereby operate the gate.

The gate-operating ropes, chains, or wires ywires 27a can obviously be placed at such an elevation as to not obstruct the passage of vehicles and yet, by means of the depending rods or. laths 35, they will be readily accessible for operating the` gate. VBy providing flexible means, such kas cords or wires 27 or 27a, for actuating the gate-levers it will be possible to operate the gate at ,any distance by drawing on said wires `or cords at any angle, suitable pulleys being arranged for supporting and guiding the wires wherever they may be required.

What I claim as my invention isl. The combination with a central post, the standard projecting centrally from the top of said post and the toothed andA segmentallyslotted disk attached to said post by means of headed studs inserted through the diskslots vertically into the post-top, of a yoke attached to the top beam of the gate and provided with a swivel-bolt, pivotally-supported disks provided with actuating-arms, and a flexible connection betweensaid disks and swivel-bolt, substantially as described.

2. The combination of the posts 25 and 28, the gravity-latch 30 and stop 31 on the inner side of a post, a centrally-pivoted, verticallymovable and horizontally-swinging gate having its opposite ends provided with pins 29 to engage the latch and stop, the central post 2 on which the gate is pivoted, an oscillatory disk 6 supported on the top of said post and provided with inclined teeth 9, rolls 17 carried bythe top beam of the gate and engaged with said teeth to turn the gate, pivotallysupported disks 22 provided with actuatingarms 26, and a swiveled connection between said disks and the top beam of the, gate, substantially as described.

3. The combination with the verticallymovable and horizontally-swinging gate 1, the central post 2 on which the gate is pivoted, the oscillatory disk 6 supported on the top of said central post and provided with inclined teeth 9, and the rolls 17 carried by IOO IIO

1o the arins 26 and adapted to be extended to any required distance from which to operate the gate, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.l
